HAY-CARRIER.

SPECIFICATION forming part of Letters Patent No. 634,949, dated October 17, 1899'.

Application filed June 26,1899. Serial No. 721,830. (No model.)

This invention relates to an improvement' whereby thevarious parts of a hay-.carrier may be put together and` taken apart more `readily and are made to operate more easily and perfectly; and it consists of the features herein described, and more particularly delined in the claims.

Figure 1 is a side view of the invention. Fig. 2 is a vertical cross-section on the line 2 2 of Fig. l, the carrier being drawn along the track-rail until this line coincides with line .fr which will operate the lock mechanism and let lthe elevating-pulley descend out of sight. Fig. 3 is a horizontal section on the line 3 3 of Fig. l, the hoisting-rope being removed and the top of the elevating-pulley being shown in outline in one position and by dotted lines in another. Fig. 4f is a crosssecton on line a 4: of Fig. 1. Fig. 5 is a perspective of the stop which is secured to the track-rail in Fig. l. Figs. 6 and 7 are views of modified forms of the locking-dog.

A represents the track-rail, and B the part of the upper frame of the carrier upon which the track-wheels C are mounted.

D is the lower frame, which is swiveled to the upper frame and carries the rope-wheels E.

F is a locking-dog, which is adapted to slide up and down in the frame B and engage and be engaged by the grapplingdiooks G1 as will .be explained hereinafter.

H is a stop adapted to be clamped to the head of the track-rail A. On its upper edges it is provided with inclined flanges I, and on the lower sides of these ilanges are abruptlyinclined shoulders J. The dogF is tted with upper lugs K, which project horizontally and are adapted to slide up on the inclined lianges I; also, with similarly-projecting lower lugs L, which are adapted to catch against the shoulders J when the dog is held in elevated position, and will thus hold the carrier stationary on the track. y

M is the hoisting-rope, which is passed over the ropewheels E, andA N is the elevatingwill drop between the upper ends of the hooks G and will hold them in that position. At thevsame time the lower lugs L of the dog F will pass below the shoulders J and will release the carrier from the stop H, and the elevating-pulley N, with its load attached, will be securely held by the grappling-hooks G while the carrier is drawn along the track. The carrier being returned to the stop H, the upper lugs K will slide up the incline I, which will lift the dog F from between the upper ends of the grappling-hooks G and allow them to turn on their pivot a and release the pulley N. In order to lighten the stop, the portion of .the upper face of the flange I opposite the shoulders J may be out out, so as to make ita uniform thickness throughout, it only being necessary to leave narrow edges on the upper face of the incline at this place for the lugs K to slide up upon. Abruptly- .inclined shoulders similar to J have beenv used for this purpose before; but when so used they have always been placed above and separate 'from the incline I, which makes the stopv clumsy, especially when affixed to the upper edge of the track-rail, and the retaining-lugs of the locking-dog have to be placed at the extreme upper end of the dog, which makes it weaker and more liable to bind the dog in its upanddowu movement than when the lugs are more centrally placed and adapted to catch on a shoulder on the lower side of the incline I, as arranged in this invention.

The stop is preferably made with doubleinclined flanges on its upper edge,having an apex in its center and abruptly-inclined shoul ders J on the lower faces ot' both flanges, so that While the dog is held in elevated position the lower lug L will be between these shoulders and the carrier will be held from When the pul-l IOO moving in either direction; but it may be made to work only in one direction, if so desired.

In order to reduce the friction in the upand-.down movement of the dog F to the minimum, I form stud pins or axles O on opposite sides of the dog F, and upon these I mount rollers P, and I form grooves or recesses in the frame ot` the carrier for these rollers to run in. As shown in Figs. I and 2, these axles O are set even with the retaining-lugs L, and when arranged in this way there will be little or no friction between the lower end of the dog F and the part of the frame in which it moves; but sometimes in adapting the dogto the frame of the carrier it may not be advantageous to do this and these axles will have to be set above the retaining-lugs L, as in Fig. 6, or below them, as in Fig. 7. In such cases I find it advisable to place additional axles O/ and rollers P on the dogs, as shown in these figures, and also provide additional grooves in the frame of the carrier for these additional rollers to run in. In this way the entire strain on the dog is borne by these upper and lower rollers and the friction upon them is reduced to a minimum. The ends of the axles or bosses O are extended out beyond the rollers P and are adapted to move up and down in slots in the frame of the carrier, thus limiting the movement of the dog F and preventingit from getting out of place.

In operation the rope M will sometimes get twisted, so that the pulley N will come up to the carrier more or lessV twisted, as indicated in Fig. 3, and to assist the pulley in straightening as it enters the carrier-frame I contract the central sides R of the carrier-frame downwardly and extend them inwardly, so as to form a guide for the frame N of the pulley N, While the side portions of the frame adjacent to the edges of the pulley-frame N are expanded outwardly, so as to make room for the pulley to enter while in a partially-twisted condition, as shown in Fig. 3. By this construction the pulley N will more readily enter the frame of the carrier and will more readily operate the lock mechanism of the carrier should the pulley become twisted or drawn to the side.

The upper frame of the carrier is composed of two side pieces B and two end pieces T, joining them together. The side pieces B are fitted with recesses or pockets V and the end pieces T with points y, adapted to enter these pockets. The lower ends of all the pieces have perforations for bolts u, and when the ends 'y are inserted in the pockets V and the bolts u are drawn up tight these pieces B and T will be held securely together and being fitted with a circular' groove on their lower edges and the frames D with a circular lip to t and turn in said groove in the usual way the upper and lower frames will be securely swiveled together.

When it is desired to take the pieces B and T apart, all that is necessary is to take out the bolts u, when the ends 'y can be readily withdrawn from the pockets V. The lower end of the dog F is preferably made circular, so that it will engage and operate the dogs G no matter in what way the swivel may be turned.

Having thus described my invention, what I claim isl. The combination of a track, a carrier adapted to run thereon, a stop secured to said track, an inclined flange on said stop and an abruptly-inclined shoulder on the under side of said flange, a dog adapted to move up and down in the frame of' the carrier and be held in elevated position therein, an upper lug on said dog adapted to slide up on said inclined fiange, and a lower lug adapted to catch against said shoulder, substantially as set forth.

2. The combination of a track, a carrier adapted to run thereon, a stop secured to said track, doubly-inclined flanges on said stop and abruptly-inclined shoulders on the lower sides of each of said flanges, adog-adapted to move upand down in the frame of the carrier and be held in elevated position therein, upper lugs on said dog adapted to slide up said inclined flanges and lower lugs adapted to catch against said shoulders, substantially as described.

3.
